LUBRICATING MECHANISM.

Application filed February 1, 1926. Serial No. 85,078.

This invention relates to lubricating mechopposite from the pump and thence through anism, and it is designed for embodiment in a passage 11 into a pan 12. When the plate connection with an internal combustion en 10 and the pan 12 are used, a baffle 13 atgine to be operated thereby as a top force tached to the plate 10 extends downwardly 6O feed lubricating system to obtain all of the from the plate and has its lower edge advantages herein specifically mentioned or spaced slightly above the bottom of the pan, otherwise made apparent from the descripleaving a passage between the lower edge of tion and drawing. the bafile and the bottom of the pan through An object of the invention is to provide which the oil passes.

vided with a sight opening 24 closed by glass or other transparent material. A valve 23 in the pipe 23 is closed during the filling of the chamber 22 and is opened after the air tight cap 22 has been replaced.

The pump is operated by an engine driven shaft when the engine is running and the o l flowing to the pump from above is forced down into the main oil reservoir andthence upwardly through a pipe 25 from which the oil distribution pipes 26 extend to discharge the oil to the parts to be lubricated In the course of operation, the heavier than oil impurities are deposited in the bottom of the main oil reservoir 1, where they remain until withdrawn through the drain outlet 27.

The invention can be manufactured and installed economically and without substantial change in standard designs of engines, and avoids and overcomes many of the difli: culties and objections in existingtypesot engines. It is apparent that the invention may be modified in various particulars without departure from the nature and principle thereof and well within the scope of the appended claims. I do not restrict myself unessentially, but what I claim and desire to secure by Letters Patent is 1.
